Welcome to my sandbox!

I’m a phD student at PMMH in Paris. I work on the interaction between turbulent flows and bubbles.

Here is the link to my website.

Codes

Bubble in turbulence

• Single bubble in an homogeneous and isotropic turbulent flow

Model flows

• Bubble in a stagnation point flow

Tools

Various interpolations

Based on the similar code by Antoon (slicer) to compute a 2D slice in a 3D simulation. All these interpolations work in 3D.

• Interpolation on a line
• Interpolation on a plane
• Interpolation on a sphere

Gaussian curvature

Modification of Basilisk files computing the average curvature to compute the gaussian curvature.

• gcurvature
• gparabola
